K5SP LONP CONGRATULATIONS

stan W9SMR
 

Yep, it is hard to believe, but Jim, K5SP, the Executive Director of our beloved PODXS 070 Club has actually found time to accumulate sufficient QSOs to grab the LONP 800 Level!

Congrats to Jim and many thanks for your dedicated efforts to ensure all members can enjoy this great group of dedicated PSK operators and friends!

Give him a fist-bump next time you see him on the waterfall.

Next milestone, 1,000!

73,

Re: PSK31 split operation

Eric KG6MZS
 

What's funny about that George is that the new versions of WJST-X can decode 3 or more signals from the same trace.  I guess the software initially decodes the strongest trace and then subtracts it from the pile and decodes other signals from whats left over.

Very different from PSK in that several signals usually renders all undecodable.  I've noticed that If I want to work a station on PSK that is getting a pileup of responses, just moving over a few hundred hertz will sometimes get me acknowledged from skilled stations.

This underlines another feature of split - the running stations needs to announce they are listening split -- unlike FT8.

It seems like the same logic would apply to any narrowband signal. Of course, as was pointed out, the PSK band is usually not crowded and you can pick a frequency in the middle.

I'll echo Stephen's sentiments.  I've seldom needed to use split for PSK because the PSK waterfall just isn't that crowded.

In Digital Master 780 it's pretty easy to set up split.  Just set up on a clear frequency and lock it, then move the receive cursor over to the station you want to work.  I usually center my TX frequency in the waterfall.

George -

Avoiding distortion is always a good thing, but I haven't seen PSK31 get distorted enough near filter-band edges to lose decode. I lose the signal power before I see a distortion.

Perhaps the m-ary FSK underlying the JT modes is more sensitive than PSK.

And remember that with splits in the few hundred Hz, proper positioning of your signal (as Eric suggested) should keep the received signals away from filter-band edges.

Re: PSK31 split operation

 

In Fldigi you do it as Eric explained to do it in DM780, use the lock button which is down at the lower right of the screen.

Re: PSK31 split operation

Stephen Melachrinos <melachri@...>
 

George -

I'll tell you my opinion, and how I implement it.

The only times I've ever operated PSK split were when I was (semi-)rare DX and I had lots of stations calling. (I was operating from a large station in KH2 back in 2012 and 2014.) Most of the time I only had one or two replies (at most) for each CQ, so it was easy to pick one out to reply to even on my frequency. Occasionally there would be so many that I couldn't even pick out a callsign fragment, so I'd go split.

I've never had to do that in any other situation, even during contests. Occasionally (like during the PSKfest last weekend) I could pick out two callsigns calling at the same time, and see enough to recognize each. I'd simply reply "two stations calling. First N7WE de W3HF..." and then at the end of that QSO send "73 N7WE de W3HF sk now KD9PCN de W3HF..." 

As to how to implement it, I find the best way is to use the software to split the Tx and Rx audio frequencies (on the waterfall), and leave the radio on a single frequency. Most software that I've seen lets you lock your Tx frequency, but move the receive around. (I use DigiPan, but I'm sure someone can tell you how to do it in fldigi.) Since you can see 2-3 kHz on the waterfall when you only need less than 100 Hz, it's easy to pick them out. My Guam CQs were something like "CQ de W3HF/KH2 up 100-300." Then with my Tx freq locked, I'd move around in the range 100-300 Hz high and find someone to reply to.

Steve

I find split operation on wsjt-x useful, and the software automates it. 
It is mentioned in the fldigi manual but looks like one would have to
set it up manually, and it's not clear which fldigi modes to use it on
(makes sense for CW, but...).  Opinion on the internet is all over the
place - some recommend it, others call it stupid.  Is there a consensus
at the 070Club?  73, KD9PCN #2879

Congratulations to LONP new members!

 

I want to also offer my CONGRATULATIONS! to all 12 of our new Members of LONP from 2021 and to 
welcome those new to 2022! 
We're 13 days into the new year, and we've got 3 new LONP'r's already!
The chase has begun and it's going to be great year for LONP!
Sitting down in front of your radio, bringing up your software program and clicking on traces...both weak and strong...
takes on a whole new meaning all full of ambitions and goals to pursue.
You YL's and OM's are doing great!
I also want to remind all members that they can get credit for working 070 Club members with membership numbers
higher than "070-2787" by sending those contacts directly to me, per the instructions on our website's Home Page at:
Good luck to all!
